castToGlobalLabeling (
        lab,
        name=None,
        removeLocal=1,
        )

cast the given labeling to a global label, if name is none the name of the local labeling is percolated to the global labeling. if removeLocal is set, the local labeling is removed. A globalWrapper analogous to the lab is returned.

subsetByLabeling (
        ds,
        labeling,
        obj,
        )

Creates and returns an arbitrary view based on a valid labeling of the dataset.

If the labeling passed is not directly tied to the dataset object, the subset returned will be the subset of self which corresponds to the datapoints labeling in the dataset to which the labeling is attatched.

The application of this behavior can be expressed in the following situation:

Given a Dataset, perform two clusterings which result in two labelings. Using these labelings, create two views, one per clustering of a particular cluster. Then create a labeling for the view which labels all the data. Now apply this labeling to the second view to create a subset of common datapoints. The code to do this may be like the following.

view1 = dataset.subset(labeling1, "cluster 2") view2 = dataset.subset(labeling2, "cluster 6")

newlabeling1 = view1.createLabeling() newlabeling1.addLabelToRows("foo", range(view1.getNumRows()))

commonGenes = view2.subset(newlabeling1, "foo")

At the conclusion of this code, the commonGenes view will hold the data which is in view2 and also labeled "foo" in newlabeling1
